I reduced the preview display resolution, thanks, it's speeded up things!
I'm not sure what I'm doing wrong, borate. I created my cropped area, created a keyframe, then started playing the video. When I got to just before the subject moved I stopped the video, created another keyframe, played the video & let the subject move, stopped the video, then left-clicked on the cropped area to create the arrowed-crosshatch and dragged the cropped window to a new position. But when I restated the video from the beginning it seems like the cropped area is following my subject? Is there a hidden setting or something?
Also, can you please explain the animation editor graph & how I can use it?
The other PITA is sometimes when I click Pause || from the Clip Preview up top, sometimes it pauses & sometimes it stops and video goes back to time index 00:00. That is really annoying!
Thank you to both of you, I really appreciate you taking the time to help me!
